[Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure are listed and described.

The wiring member of the present disclosure is as follows.

(1) A first linear transmission member, a second linear transmission member that is more susceptible to bending deformation than the first linear transmission member, and the first linear transmission member and the second linear transmission member are fixed. a base member, wherein the first linear transmission member is fixed to the base member via a plurality of first fixing parts, and the second linear transmission member is fixed via a plurality of second fixing parts The plurality of first fixing portions fixed to the base member are arranged at a first pitch in a direction along the first linear transmission member, and the plurality of second fixing portions are arranged at the second linear transmission member. wiring members arranged at a second pitch smaller than the first pitch in a direction along the .

According to the present disclosure, the first linear transmission member is fixed to the base member via a plurality of first fixing portions arranged at a first pitch larger than the second pitch. Since the first linear transmission member is less prone to bending deformation than the second linear transmission member, the first linear transmission member is less likely to flutter on the base member. Therefore, it is possible to reduce the number of fixing points while suppressing fluttering of the first linear transmission member. On the other hand, the second linear transmission member is more susceptible to bending deformation than the first linear transmission member. The second linear transmission member is fixed to the base member via a plurality of second fixing portions arranged at a second pitch smaller than the first pitch. This makes it difficult for the second linear transmission member to flutter on the base member. Therefore, as a whole wiring member, the first linear transmission member and the second linear transmission member are fixed to the base member at a small number of fixing locations while suppressing flapping. As a result, the linear transmission member is easily fixed to the base member.

(2) In the wiring member of (1), the second linear transmission member may be thinner than the first linear transmission member. As a result, the first linear transmission member, which is thicker than the second linear transmission member, is fixed to the base member at fewer fixing points.

(3) In the wiring member of (1) or (2), the first fixing portion is a portion for welding and fixing the first linear transmission member to the base member, and the second fixing portion is the second fixing portion. It may be a wiring member, which is a portion for welding and fixing the two-line transmission member to the base member. In this case, the portion to be fixed by welding is reduced, and the linear transmission member is easily fixed to the base member.

(4) In the wiring member according to any one of (1) to (3), the plurality of first fixing portions extend linearly through at least a portion of the first linear transmission member and extend from the base. A wiring member may be fixed to a member, and the plurality of second fixing portions may be a wiring member that fixes at least part of the second linear transmission member to the base member in a linearly extending state. A portion of the first linear transmission member that extends linearly and is fixed to the base member has fewer fixing points.

(5) In the wiring member according to any one of (1) to (4), a portion of the first linear transmission member and at least a portion of the second linear transmission member extend along a common path. is fixed to the base member, another part of the first linear transmission member is fixed to the base member along a branch path branched from the second linear transmission member, and in the branch path, the second linear transmission member The other portion of the one linear transmission member is fixed to the base member via the plurality of first fixing portions, and the at least the portion of the second linear transmission member is connected to the second linear transmission member on the common path. The wiring is fixed to the base member via a fixing portion, and further, the part of the first linear transmission member is fixed to the base member via a plurality of fixing portions arranged at the second pitch. It may be a member. In the common path, part of the first linear transmission member and at least part of the second linear transmission member are efficiently fixed to the base member at the same second pitch.

(6) The wiring member according to any one of (1) to (5), which is more susceptible to bending deformation than the first linear transmission member and less prone to bending deformation than the second linear transmission member. A third linear transmission member is provided, the third linear transmission member is fixed to the base member via at least a plurality of third fixing portions, and the plurality of third fixing portions are connected to the third linear transmission member. The wiring members may be arranged at a third pitch smaller than the first pitch and larger than the second pitch in a direction along the . The fixed pitch is set by further subdividing according to the bending deformability of the linear transmission member. As a result, the first linear transmission member, the second linear transmission member, and the third linear transmission member are fixed to the base member at a small number of fixing points as a whole while suppressing flapping.

[Details of the embodiment of the present disclosure]
A specific example of the wiring member of the present disclosure will be described below with reference to the drawings. The present disclosure is not limited to these examples, but is indicated by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.

[Embodiment 1]
The wiring member according to the first embodiment will be described below. FIG. 1 is a schematic plan view showing a wiring member 20 according to Embodiment 1. FIG. The wiring member 20 includes a first linear transmission member 30 , a second linear transmission member 40 and a base member 22 .

It is assumed that the first linear transmission member 30 and the second linear transmission member 40 are linear transmission members that connect parts of the vehicle. The first linear transmission member 30 and the second linear transmission member 40 extend along wiring paths according to the positions of the components to be connected.

More specifically, the linear transmission member may be any linear member that transmits electricity, light, or the like. For example, the linear transmission member may be a general electric wire having a core wire and a coating around the core wire, or may be a bare conductor wire, a shielded wire, a twisted wire, an enameled wire, a nichrome wire, an optical fiber, or the like. .

Various signal lines and various power lines may be used as linear transmission members for transmitting electricity. A part or the like of a linear transmission member that transmits electricity may be used as an antenna, a coil, or the like that transmits or receives signals or power to or from space.

In addition, the linear transmission member may be a single linear object, or a composite of multiple linear objects (twisted wire, a cable in which a plurality of linear objects are assembled and covered with a sheath, etc.). ).

Here, the description is mainly based on the assumption that the first linear transmission member 30 is the first electric wire 30 and the second linear transmission member 40 is the second electric wire 40 .

The second linear transmission member 40 is more prone to bending deformation than the first linear transmission member 30 . For example, whether bending deformation is easy or not depends on bending rigidity. For example, the bending stiffness of the second linear transmission member 40 is lower than the bending stiffness of the first linear transmission member 30 . Whether or not the first linear transmission member 30 or the second linear transmission member 40 is more prone to bending deformation is determined by, for example, a bending test such as a three-point bending test or a four-point bending test under normal temperature environment. It may be determined, for example, by measuring the force from a predetermined initial state (eg straight state) to a predetermined deformed state in a test.

In general, a thin linear body is more susceptible to bending deformation than a thick linear body. In this embodiment, an example in which the second electric wire 40 is thinner than the first electric wire 30 will be described.

In addition, when the physical properties of the material itself constituting the first linear transmission member 30 and the physical properties of the material itself constituting the second linear transmission member 40 are significantly different, a thick linear body may be used. It may become easier to bend and deform than a thin filamentous body. For example, assume that the first linear transmission member and the second linear transmission member are electric wires. PVC (polyvinyl chloride), PE (polyethylene), or the like can be used as the coating of the electric wire. PVC is generally more flexible than PE. Therefore, the PVC-coated wire tends to be easily bent and deformed, while the PE-coated wire tends to be difficult to bend. In such a case, even if the first linear transmission member is thinner than the second linear transmission member, the second linear transmission member may be more susceptible to bending deformation than the first linear transmission member.

The base member 22 is a member to which the first electric wire 30 and the second electric wire 40 are fixed. The base member 22 has a main surface 23, and the first electric wire 30 and the second electric wire 40 are fixed on the main surface 23 so that the first electric wire 30 and the second electric wire 40 are fixed to a predetermined distance. retained along the path. That is, it can be said that the base member 22 is a member having the main surface 23 that holds the first electric wire 30 and the second electric wire 40 along a predetermined path. The base member 22 may be a member having the main surface 23 for fixing the first electric wire 30 and the second electric wire 40 as described above, and may be formed in a sheet shape or a three-dimensional shape. may be formed in The main surface 23 may be a flat surface, a curved surface, an uneven surface, or a surface in which a flat surface and other curved surfaces are combined.

Here, the base member 22 will be described as a member having a flattened portion, more specifically a bendable sheet member 22 .

The sheet member 22 may be formed in a shape along the wiring path of the first electric wires 30 and the second electric wires 40 . Here, the sheet member 22 comprises a first strip-shaped portion 24 and a second strip-shaped portion 26 . The first strip-shaped portion 24 is formed in an elongated rectangular shape. The second strip-shaped portion 26 is also formed in an elongated rectangular shape. The second belt-shaped portion 26 extends from the proximal end portion of the first belt-shaped portion 24 in a direction orthogonal to the extending direction of the first belt-shaped portion 24 . That is, the sheet member 22 has a shape in which the first strip-shaped portion 24 and the second strip-shaped portion 26 are connected in an L-shape. The sheet member may be formed straight or may be curved in various directions. The sheet member may have a curved portion. The sheet member 22 may have branched portions.

The material forming the sheet member 22 is not particularly limited, but the sheet member 22 is preferably made of a material containing a resin such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), or PP (polypropylene). be. The sheet member 22 may be a sheet material whose interior is uniformly filled, or may be a non-woven sheet or the like. Sheet member 22 may also comprise a material such as metal. The sheet member 22 preferably has flexibility to be easily bent in the thickness direction. The sheet member 22 may be a single layer, or may be laminated in multiple layers. When a plurality of layers are laminated, for example, it is conceivable that the sheet member 22 is formed by laminating resin layers and resin layers. More specifically, for example, the sheet member 22 is considered to be a laminate of a resin sheet material and a non-woven sheet, the inside of which is evenly filled. Further, for example, the sheet member 22 may be formed by laminating a resin layer and a metal layer.

A first electric wire 30 is fixed to the sheet member 22 via a plurality of first fixing portions 36 . The first electric wire 30 may be fixed to the sheet member 22 via another fixing portion in addition to the plurality of first fixing portions 36 . For example, at least some sections of the first electric wires 30 are fixed to the sheet member 22 via a plurality of first fixing portions 36, and other sections of the first electric wires 30 are fixed to the sheet member via other fixing portions. 22 may be fixed.

A second electric wire 40 is fixed to the sheet member 22 via a plurality of second fixing portions 46 . In addition to the plurality of second fixing portions 46, the second electric wires 40 may be fixed to the sheet member 22 via another fixing portion in the same manner as described above.

As a fixing mode of the first electric wire 30 and the second electric wire 40 to the sheet member 22, if the first electric wire 30 or the second electric wire 40 is fixed to the sheet member 22 at a partial location in the longitudinal direction. It may be contact site fixation or non-contact site fixation. Here, the contact portion fixation means that the contact portion between the first electric wire 30 or the second electric wire 40 and the sheet member 22 is attached and fixed. Non-contact site fixation is a fixation mode that is not contact site fixation. The non-contact part fixation is, for example, a fixing member such as a sewing thread or an adhesive tape that presses the first electric wire 30 or the second electric wire 40 toward the sheet member 22 to maintain the pressed state. is. In the following description, the first electric wire 30 or the second electric wire 40 and the sheet member 22 are assumed to be in a fixed contact portion state.

Such contact site fixation may be indirect fixation at the contact site, direct fixation at the contact site, or both may be used in different regions. Here, the indirect fixing of the contact portion means that the first electric wire 30 or the second electric wire 40 and the sheet member 22 are indirectly fixed via an indirect fixing portion such as an adhesive, an adhesive, or a double-sided adhesive tape provided between them. It is stuck and fixed. Further, the direct fixation of the contact portion means that the first electric wire 30 or the second electric wire 40 and the sheet member 22 are directly attached and fixed without an adhesive or the like provided separately. In the direct fixation of the contact portion, for example, resin contained in at least one of the first electric wire 30 or the second electric wire 40 and the sheet member 220 is melted, so that they are stuck and fixed.

In forming such a state in which the contact portion is directly fixed, the resin may be melted, for example, by heat or melted by a solvent. That is, the state of direct fixation of the contact portion may be the state of direct fixation of the contact portion by heat or the state of direct fixation of the contact portion by solvent. Preferably, the contact portion is directly fixed by heat.

At this time, the means for forming the state of direct fixation of the contact portions is not particularly limited, and known means such as welding, fusing, and welding can be used. For example, when the contact portion is directly fixed by heat by welding, various welding means such as ultrasonic welding, heat-pressure welding, hot-air welding, and high-frequency welding can be employed. Further, when the contact portion directly fixed state is formed by these means, the first electric wire 30 or the second electric wire 40 and the sheet member 22 are brought into the contact portion directly fixed state by the means. Specifically, for example, when a state in which the contact portion is directly fixed by ultrasonic welding is formed, the first electric wire 30 or the second electric wire 40 and the sheet member 22 are in a state in which the contact portion is directly fixed by ultrasonic welding. be done. Here, it is assumed that the first fixing portion 36 is a portion that welds and fixes the first electric wire 30 to the sheet member 22, and the second fixing portion 46 is a portion that welds and fixes the second electric wire 40 to the sheet member 22. An explanation is provided. In particular, the description assumes that these welded and fixed portions are portions fixed by ultrasonic welding. That is, the first fixed portion 36 is a spot-welded portion where the resin forming the sheet member 22 and the resin forming the coating of the first electric wire 30 are fixed by ultrasonic welding. The second fixed portion 46 is a spot-welded portion where the resin forming the sheet member 22 and the resin forming the covering of the second electric wire 40 are fixed by ultrasonic welding.

The first electric wire 30 is fixed onto the main surface of the first belt-shaped portion 24 of the sheet member 22 . Here, the first electric wire 30 extends linearly along the longitudinal direction of the first strip-shaped portion 24 . The plurality of first fixing portions 36 fix at least linearly extending portions of the first electric wires 30 to the sheet member 22 . Here, that the first electric wires 30 extend linearly means that the first electric wires 30 are not bent when the main surface 23 of the sheet member 22 is observed in a plan view. More preferably, the first electric wire 30 extends linearly in a direction perpendicular to the main surface 23 without straddling other electric wires, in addition to the observation state of the planar view. It means that it is not bent even in Note that the first fixing portion may fix the first electric wire to the sheet member in a bent state. A portion of the first electric wire other than the portion fixed by the first fixing portion may be bent and fixed to the sheet member.

The second electric wire 40 is fixed onto the main surface of the second belt-like portion 26 of the sheet member 22 . Here, the second electric wire 40 extends linearly along the longitudinal direction of the second belt-shaped portion 26 . The plurality of second fixing portions 46 fix at least linearly extending portions of the second electric wires 40 to the sheet member 22 . Here, the linear extension of the second electric wire 40 may be grasped in the same manner as the case of the linear extension of the first electric wire 30 . The second fixing portion may fix the second electric wire to the sheet member in a bent state. A portion of the second electric wire other than the portion fixed by the second fixing portion may be bent and fixed to the sheet member.

One end of the first wire 30 extends from the tip of the first belt-shaped portion 24 and is connected to the connector 60 . One end of the second electric wire 40 extends from the tip of the second belt-shaped portion 26 and is connected to the connector 62 . The other end of the first electric wire 30 extends from the first strip-shaped portion 24 to the base end of the second strip-shaped portion 26, bends into an L shape at the base end of the second strip-shaped portion 26, and extends to the base of the second strip-shaped portion 26. It extends outwardly from the end. The other end of the second electric wire 40 extends outward from the base end of the second belt-shaped portion 26 . The other end of the first wire 30 and the other end of the second wire 40 are connected to the connector 64 . The end of each electric wire may be connected to the connector without extending from the sheet member. In this case, the connector may be fixed to the sheet member.

In this embodiment, only one first wire 30 and only one second wire 40 are shown. The wiring member 20 may include a plurality of first electric wires 30 or may include a plurality of second electric wires.

In the direction along the first electric wire 30, the multiple first fixing portions 36 are arranged at a first pitch P1. Here, the pitch is the distance between the fixed parts in the direction along the wire, for example, the distance between the centers of the fixed parts. In the direction along the second electric wire 40, the plurality of second fixing portions 46 are arranged at a second pitch P2. The second pitch P2 is smaller than the first pitch P1. The first pitch P1 is set to a size that prevents the first wires 30 from flapping from the sheet member 22 in consideration of the difficulty of bending deformation of the first wires 30 and the like. The second pitch P2 is set to a size that prevents the second electric wires 40 from flapping from the sheet member 22 in consideration of the easiness of bending deformation of the second electric wires 40 and the like. Normally, a linear body that is easily bent and deformed easily bends between fixing points, and thus easily flaps against a fixing target. In addition, since the linear body, which is difficult to be bent and deformed, is difficult to bend between fixing points, it is difficult to flutter with respect to the fixing target. Therefore, the first electric wires 30 that are difficult to bend and deform are fixed to the sheet member 22 at a first pitch P1 that is larger than the second pitch P2. Further, the second electric wires 40 that are easily bent and deformed are fixed to the sheet member 22 at a second pitch P2 that is smaller than the first pitch P1. If each electric wire is fixed such that at least one first pitch P1 out of the fixed pitches of the first electric wires is larger than at least one second pitch P2 out of the fixed pitches of the second electric wires. good. For example, when considering the wiring space of the wiring member, the wiring work, and the packing style during transportation, a part of the fixed pitch for fixing the first electric wire is smaller than or equal to the second pitch P2. It can be pitch. Even in the above case, if the first pitch P1 of at least one of the fixed pitches of the first wires is larger than the second pitch P2 of at least one of the fixed pitches of the second wires, the linear transmission member can be easily fixed to the base member.

According to the wiring member 20 configured in this manner, the first electric wires 30 are fixed to the sheet member 22 via the plurality of first fixing portions 36 arranged at the first pitch P1 larger than the second pitch P2. be. Since the first electric wires 30 are less prone to bending deformation than the second electric wires 40 , the first electric wires 30 are less likely to flutter on the sheet member 22 . Therefore, for the first electric wire 30, the first pitch P1 can be increased to the extent that flapping can be suppressed, and the number of fixed locations can be reduced. On the other hand, the second electric wire 40 is more prone to bending deformation than the first electric wire 30 . Therefore, the second electric wires 40 are fixed to the sheet member 22 via a plurality of second fixing portions 46 arranged at a second pitch smaller than the first pitch P1. This makes it difficult for the second electric wires 40 to flutter on the sheet member 22 . As a result, the wiring member 20 as a whole is fixed to the sheet member 22 at a small number of fixing points while suppressing the fluttering of the first electric wires 30 and the second electric wires 40 . As a result, the first electric wires 30 and the second electric wires 40 are easily fixed to the sheet member 22 .

Further, if the first electric wires 30 are thicker than the second electric wires 40 and the second electric wires 40 are thinner than the first electric wires, the thick first electric wires 30 are fixed to the sheet member 22 at fewer fixing locations, and the thin second electric wires are fixed. is fixed to the sheet member 22 in a state in which flapping is effectively suppressed at many fixing points.

If the first fixing portion 36 and the second fixing portion 46 are welded and fixed portions, the number of welded and fixed portions is reduced. As a result, the first electric wires 30 and the second electric wires 40 are easily fixed to the sheet member 22 with a small amount of welding work.

The fixed pitch of the electric wires may be examined by separately considering the holding strength with respect to the sheet member, etc. at the bending points and crossing points. If the portion fixed by the first fixing portion 36 on the first electric wire 30 is a portion extending linearly, and the portion fixed by the second fixing portion 46 on the second electric wire 40 is a portion extending linearly, there are separate consideration factors. The first pitch P1 and the second pitch P2 can be determined by excluding them as much as possible. In this case, the portion of the first electric wire 30 that extends linearly and is fixed to the sheet member 22 has fewer fixing points.

In the case where there are multiple types of electric wires with different easiness of bending deformation, if the multiple types of electric wires are fixed to the base member at pitches that prevent the most easily deformable electric wire from fluttering, the number of fixing points increases. , the work of fixing the electric wire becomes troublesome. In this wiring member, a plurality of types of electric wires can be fixed to the base member at a pitch corresponding to the ease of bending deformation.

In the wiring member, there are cases where three or more types of electric wires with different easiness of bending deformation are fixed to the base member. In such a case, any of the three or more types of electric wires may be grasped as the second electric wire and any of them may be grasped as the second electric wire. For example, the wire that is least deformable among the three or more types of wires may be the first wire, and the wire that is the most deformable among the three or more types of wires may be the second wire. When three or more types of electric wires with different easiness of bending deformation are fixed to the base member, the fixed pitch of the electric wires may be divided into three or more stages. Such a form is described in Embodiment 4 below.

[Embodiment 2]
A wiring member 120 according to the second embodiment will be described. FIG. 2 is a schematic plan view showing the wiring member 120. FIG. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted, and differences from the first embodiment are mainly described.

In this wiring member 120 , the route of the first electric wire 130 is different from the route of the first electric wire 30 in the wiring member 20 .

That is, the first electric wire 130 is less likely to bend than the second electric wire 40, like the first electric wire 30 described above. One end portion of the first electric wire 130 is fixed onto the main surface of the first belt-shaped portion 24 . On the first strip-shaped portion 24 , the first electric wire 130 extends linearly along the longitudinal direction of the first strip-shaped portion 24 . The intermediate portion of the first electric wire 130 is bent in an L shape at the portion where the first strip-shaped portion 24 and the second strip-shaped portion 26 intersect. The other end portion of the first electric wire 130 is fixed onto the main surface of the second belt-shaped portion 26 . On the second belt-shaped portion 26 , the first electric wire 130 extends linearly along the longitudinal direction of the second belt-shaped portion 26 .

The other end portion of the first electric wire 130 runs along the portion of the second electric wire 40 on the second strip portion 26 . Therefore, the other end portion, which is a part of the first electric wire 130 , and at least a part of the second electric wire 40 are sheet-shaped along a common path along the longitudinal direction of the second strip-shaped portion 26 . It is fixed to member 22 .

The other one end portion of the first electric wire 130 is a sheet member along a branched route (here, a route along the longitudinal direction of the first belt-shaped portion 24 ) branched from the second electric wire 40 . 22 is fixed. As in the first embodiment, the one end portion of the first electric wire 130 is fixed to the sheet member 22 at the first pitch P1 via the plurality of first fixing portions 36 .

In the common path, at least some of the second electric wires 40 are fixed to the sheet member 22 at the second pitch P2 via the plurality of second fixing portions 46, as in the first embodiment. Furthermore, in this common path, the other end portion of the first electric wire 130 is fixed to the sheet member 22 via a plurality of fixing portions 136 arranged at the second pitch P2. That is, in the common path, the other end portion of the first electric wire 130 and at least part of the second electric wire 40 are fixed to the sheet member 22 at the same second pitch P2. It is preferable that the plurality of second fixing portions 46 and the plurality of fixing portions 136 not only have the same pitch, but also be provided at the same position in the direction along the common path.

According to this modification, since the fixed pitch of the first electric wires 130 and the fixed pitch of the second electric wires 40 are the same second pitch P2 in the common path, the work of fixing them is facilitated. For example, when welding the second electric wire 40 to the other end portion of the first electric wire 130 running parallel to the second belt-shaped portion 26, a member for applying welding energy (a heating mold, a superheater, etc.) If a tip, anvil, etc. for sonic welding is used that is larger than the parallel width of the first electric wire 130 and the second electric wire 40, the first electric wire 130 and the second electric wire 40 can be welded at the same time. In such a case, the first electric wires 130 and the second electric wires 40 can be easily fixed collectively to the sheet member 22 at the same second pitch P2 on the common path. Of course, regardless of the fixing work described above, if the fixing pitches for a plurality of electric wires are the same, the fixing work can be facilitated because the devices, settings, etc. for the fixing work are shared.

When a plurality of types of wires with different easiness of deformation are arranged in parallel, the plurality of types of wires may be fixed to the base member at a pitch that matches the type of wire that is most easily deformed.

A modification according to the second embodiment is shown in FIG. As shown in FIG. 3, in the second embodiment, a second strip 226 corresponding to the second strip 26 may have an extension 226a extending beyond the first strip 24 . Also, the second electric wire 240 corresponding to the second electric wire 40 may further extend beyond the location where the first electric wire 130 branches. The other end of the second electric wire 240 is fixed on the extended portion 226a of the second belt-shaped portion 226. As shown in FIG. The other end of the second electric wire 240 does not share the route with the first electric wire 130 . The other end of the second electric wire 240 is fixed to the extension portion 226a via a plurality of second fixing portions 246. As shown in FIG. The pitch of the plurality of second fixing portions 246 is the second pitch P2 described above. Therefore, the other end of the second electric wire 240 is also fixed to the extended portion 226a at a pitch suitable for suppressing flapping.

[Embodiment 3]
A wiring member 320 according to the third embodiment will be described. FIG. 4 is a schematic plan view showing the wiring member 320. FIG. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted, and differences from the first embodiment are mainly described.

In this wiring member 320 , a sheet member 322 corresponding to the sheet member 22 includes a third band-shaped portion 328 . The third strip-shaped portion 328 is formed in an elongated strip shape. The third strip-shaped portion 328 extends from the base end of the second strip-shaped portion 26 perpendicularly to the extending direction of the second strip-shaped portion 26 to the opposite side of the first strip-shaped portion 24 . That is, the sheet member 322 has a shape in which the first belt-shaped portion 24, the second belt-shaped portion 26, and the third belt-shaped portion 328 are connected in a T-shape. The sheet member may have a curved portion or a branched portion.

The wiring member 320 also includes a third linear transmission member 350 . The third linear transmission member 350 may be a linear member that transmits electricity, light, or the like, like the linear transmission member described in the first embodiment. Here, the third linear transmission member 350 is described as being the third electric wire 350 .

The third electric wire 350 is more prone to bending deformation than the first electric wire 30 and less prone to bending deformation than the second electric wire 40 . For example, the third electric wire 350 is thinner than the first electric wire 30 and thicker than the second electric wire 40 .

At least part of the third electric wire 350 is fixed to the sheet member 322 via a plurality of third fixing portions 356 . Here, one end of the third electric wire 350 extends from the tip of the third belt-shaped portion 328 and is connected to the connector 360 . The other end of the third electric wire 350 reaches the base end of the second strip-shaped portion 26 from the third strip-shaped portion 328, bends in an L shape at the base end of the second strip-shaped portion 26, and extends to the base of the second strip-shaped portion 26. It extends outwardly from the end. The other end of the third wire 350 of the third wire 350 is connected to the connector 64 . The third electric wire 350 extends linearly in the longitudinal direction of the third strip-shaped portion 328 .

In this embodiment, only one third electric wire 350 is illustrated. The wiring member 320 may include multiple third wires 350 .

The multiple third fixing portions 356 are arranged at a third pitch P3 in the direction along the third electric wire 350 . The third pitch P3 is smaller than the first pitch P1 and larger than the second pitch P2. Since the third electric wire 350 is more easily deformed than the first electric wire 30 , the third electric wire 350 is more likely to flutter than the first electric wire 30 . Therefore, the third electric wires 350 are fixed to the sheet member 322 at a third pitch P3 that is smaller than the first pitch P1 suitable for the first electric wires 30 . Further, the third electric wire 350 is less likely to be deformed than the second electric wire 40 , and thus is less likely to flutter than the second electric wire 40 . Therefore, the third electric wires 350 are fixed to the sheet member 322 at a third pitch larger than the second pitch P2 suitable for the second electric wires 40 .

According to this embodiment, the fixed pitch is set by subdividing into three or more stages according to the bending deformability of the electric wires 30 , 40 , 350 . As a result, when there are three or more types of easiness of bending deformation, the first electric wire 30, the second electric wire 40, and the third electric wire 350 are suppressed from fluttering, and the fixing points of the wiring member 320 as a whole are reduced. . Thereby, the first electric wire 30 , the second electric wire 40 and the third electric wire 350 are easily fixed to the sheet member 322 .

Note that the configurations described in the above embodiments and modifications can be appropriately combined as long as they do not contradict each other. For example, as described in the second embodiment, a configuration in which linear transmission members with different easiness of bending deformation are arranged along a common path, and three or more types of wiring members with different easiness of bending deformation. may be combined with a configuration comprising a linear transmission member.
